That's not Crocodile Dundee, it's Stakey Dundee... and that's not a knife, it's a fork... or not a fork? Let me clear this up for you...
The Stakey Dundee, "That's not a fork!" sticker, pictured above, was part of the SWAG on offer at the Decred - Touchdown Australia! meetup. It was one of two stickers where Stakey was given an Aussie icon makeover, accompanied by an adapted version of one of their famous sayings. You can check out the other sticker here.
Stakey represents the proof-of-stake mining ticket system used by the Decred cryptocurrency. This system allows Decred holders to stake their coins in order to have a say in the decisions that influence the future direction of the project. Sweet, just like the SWAG.
